- 2. RECAP • Present Data in Textual and Tabular Format Problems--------- 02
- 3. LEARNING OBJECTIVES • After Studying this unit, the students able to know how to present data Graphically using Histogram, Frequency Polygon and Curve, and Pie charts and working out cumulative frequency
- 4. LEARNING OUTCOMES • Students will be able to analyze and interpret with in the Contexts they are written in Diagrams and to present data Graphically using Histogram, Frequency Polygon and Curve, and Pie charts
- 5. SESSION - 18 • Introduction, Types of Diagrams
- 6. Introduction of Diagrams • Diagrammatic Presentation of Data gives an immediate understanding of the real situation to be defined by data in comparison to the tabular presentation of data or textual representations. • Diagrammatic presentation of data translates pretty effectively the highly complex ideas included in numbers into more concrete and quickly understandable form. • Diagrams may be less certain but are much more efficient than tables in displaying the data.
- 7. CONTD • General Guidelines of Diagrams Title – Every diagram must be given a suitable ‘Title’ which should be small and self-explanatory. Size – Size of the diagram should be appropriate neither too small nor too big. Paper used – Diagrams are generally prepared on blank paper. Scale – Under one-dimensional diagrams especially ‘Bar Diagrams’ generally Y-axis is more important from the point of view of the decision of scale because we represent magnitude along this axis. Index – When two or more variables are presented and different types of line/shading patterns are used to distinguish, then an index must be given to show their details. Selection of Proper Type of Diagram – It’s very important to select the correct type of diagram to represent data effectively.
- 8. Types of Diagrams • Diagrams are various geometrical shape such as bars, circles etc. Diagrams are based on scale but are not confined to points or lines. They are more attractive and easier to understand than graphs. • Types of Diagrams 1. One Dimensional Bar Diagram ( Simple and Sub Divided Bar Diagram Percentage and Sub Multiple Bar Diagram) 2. Two Dimensional Bar Diagram (Squares, Pie Diagram and Rectangle Bar Diagram)
